PS1-5-1 Develop a model to describe that matter is made of particles too small to be seen.
PS1-5-1.PS1.A Structure and Properties of Matter
PS1-5-1.PS1.A.i Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects.
PS1-5-2 Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
PS1-5-2.PS1.A Structure and Properties of Matter
PS1-5-2.PS1.A.i The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish.
PS1-5-3 Make observations and measurements to identify materials based on their properties.
PS1-5-3.PS1.A Structure and Properties of Matter
PS1-5-3.PS1.A.i Measurements of a variety of properties can be used to identify materials. (Boundary: At this grade level, mass and weight are not distinguished, and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation.)
LS2-5-4 Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change.
LS2-5-4.LS2.C Ecosystem Dynamics, Functioning, and Resilience
LS2-5-4.LS2.C.i When the environment changes in ways that affect a place's physical characteristics, temperature, or availability of resources, some organisms survive and reproduce, others move to new locations, yet others move into the transformed environment, and some die.
ESS1-5-1 Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from the Earth.
ESS1-5-1.ESS1.A The Universe and its Stars
ESS1-5-1.ESS1.A.i The sun is a star that appears larger and brighter than other stars because it is closer. Stars range greatly in their distance from Earth.
ESS1-5-2 Represent data in graphical displays to reveal patterns of daily changes in length and direction of shadows, day and night, and the seasonal appearance of some stars in the night sky.
ESS1-5-2.ESS1.B Earth and the Solar System
ESS1-5-2.ESS1.B.i The orbits of Earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. These include day and night; daily changes in the length and direction of shadows; and different positions of the sun, moon, and stars at different times of the day, month, and year.
ESS2-5 Earth's Systems
ESS2-5-1 Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
ESS2-5-1.ESS2.A Earth Materials and Systems
ESS2-5-1.ESS2.A.i Earth's major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth's surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather.
ESS2-5-2 Describe and graph the amounts and percentages of water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.
ESS2-5-2.ESS2.C The Roles of Water in Earth's Surface Processes
ESS2-5-2.ESS2.C.i Nearly all of Earth's available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.
ESS3-5-1 Support, obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment.
ESS3-5-1.ESS3.C Human Impacts on Earth Systems
ESS3-5-1.ESS3.C.i Human activities in agriculture, industry, and everyday life have effects on the land, vegetation, streams, ocean, air, and even outer space. Individuals and communities are doing things to help protect Earth's resources and environments.
